• the invention relates to a winding aid device and a method for winding a component by means of a wire as well as a winding machine.
• WO 2018 069 298 A1 describes a method for winding the winding teeth of a rotor or stator of an electric machine using a winding aid and a needle winding device.
• a winding aid is placed on the axially facing end of the rotor or stator and detachably connected to the rotor or stator.
• the winding teeth and the winding aid are then wound with a winding wire using needle winding technology, with the winding wire being deflected in the region of the winding aid, and the winding aid being removed again after the rotor or stator has been completely wound.
• the winding aid comprises a plurality of wire guide elements, with each winding tooth to be wound being assigned a wire guide element, and the wire guide element having a winding tooth extension section designed to extend the winding tooth in the axial direction.
• Each wire guide element of this winding aid is attached to the rotor or stator prior to winding by means of at least one pin or bolt, so that the transverse forces occurring during winding do not cause individual wire guide elements to shift in the circumferential direction, which could disrupt the winding process.
• the grooves between the winding teeth remain open, and any winding pattern can be implemented without being restricted by the winding aid.
• the attachment of the individual wire guide elements to the winding teeth prior to winding and the subsequent removal of the wire guide elements with a involves a considerable amount of time and manual work.
• plastic end caps can be used on the end faces of the winding teeth. These caps serve to guide the wire in the winding head and insulate the coil bodies from the laminated core. This is the case, for example, in DE 10 2011 008 662 A1 Such plastic end caps are wound along with the laminated cores during winding. They therefore remain on the rotor or stator. Attaching the plastic end caps takes relatively little time, and the laborious removal of the plastic end caps can be eliminated.
• the use of end caps results in disadvantages due to different wire lengths for different phases, which negatively impact the power density of different phases of an electric machine.
• Stators with distributed windings are not typically wound directly using needle winding technology. Instead, a pull-in process is used. In the pull-in process, windings are first created as so-called field coils on a first machine. Only then are the windings removed from the field coils and axially drawn as a whole into a rotor or stator to be wound on a second machine using a translational movement.
• the pull-in process is not suitable for winding stators or rotors with skew-grooved internal winding teeth. Motors with skew-grooved stators or rotors have better running characteristics and lower noise levels.

• the carriage 51 can be held radially stationary while the actuating carriage 31 is moved in the radial direction R.
• the deflection of the actuating lever 33 changes, so that the actuating lever 33 pivots the winding hook 3.
• the actuating lever 33 can be displaced by holding the carriage 51 radially stationary while the actuating carriage 31 is urged outwards in the radial direction R by the second link 8.
• the second driver 81 fastened to the actuating carriage 31 is displaced in the radial direction R.
• a rotation of the second link 8 relative to the first link 7 can be achieved by rotating the actuating register 80 relative to the carriage register 70 about the central axis M.
• the registers 70, 80 are in the winding position according to the Figures 5D and 8 spread further apart than in the release position according to the Figures 6D and 9 .
• a locking element for actuating one or both actuating registers 70/80 can be provided on the machine side, in particular stationary on a frame of the winding machine 100 (not shown in detail).
• a locking element can be displaceable between an active position for actuating an actuating register 70 and/or 80 and a passive position in which the actuating register(s) 70 and/or 80 remain unaffected by the locking element.
• the locking element can be displaceable in the axial direction A and/or radial direction R between the active and the passive position.
• the locking element In the active position, the locking element can be brought into contact engagement with an actuating register 70/80, in particular of the auxiliary winding device 1, in order to displace the actuating register 70/80 relative to the corresponding link 7/8 about the central axis. In this way, the winding hooks can be moved into the winding position, the removal position and/or the release position by means of a rotational movement of the winding auxiliary device 1.
